Question

Subtract (By both methods horizontal, vertical)
xy3 + 2xy2 - xy +2 from – xy2 – 3xy3 + 2xy​

Answer 1

Answer:

2xy^3+3xy+2xy^2+2-xy^2

Step-by-step explanation:

-xy^2-3xy^3+2xy—(xy^3+2xy^2-xy+2)

= -xy^2-3xy^3+2xy – xy^3-2xy^2+xy-2

= -3xy^3+xy^3+2xy+xy+2xy^2+2-xy^2

= -2xy^3+3xy+2xy^2+2-xy^2
